Reply to inzone ilysaml a c 143 U Graphics card May 8, 2012 9:17:48 PM Yes, but PCIE 3.0/2.0/2.1 cards sometimes don't work with PCIE 1.0/1.1 slots unless the manufacturer provide a BIOS update support this.

Reply to bergami inzone a c 182 U Graphics card May 8, 2012 9:24:16 PM Video cards do not fully fill up the bandwith of the Pci-e 2.0 slot or the Pci-e 2.1 slot so yes your card is maximized and it doesn't need the Pci-e 3.0 slot. Reply to inzone ilysaml a c 143 U Graphics card May 8, 2012 9:24:23 PM Yes it. PCIE 2.1 is the same as PCIE 2.0 Quote:PCI Express 2.1 supports a large proportion of the management, support, and troubleshooting systems planned for full implementation in PCI Express 3.0. However, the speed is the same as PCI Express 2.0. Reply to ilysaml bergami May 8, 2012 9:36:14 PM Best answer selected by bergami.
